The box seems very unsubstantial. I even saw one in the store that was cracked. I didn't realize how cheap the construction was until I got home and compared it to other file boxes I previously purchased.
A nice sized box that can be used for either letter OR legal size hanging folders. My only complaint is the plastic material it is made of is rather brittle. If you plan on moving these boxes around much note they are prone to being damaged. I hit one on the edge of the desk not hard and now it has a long crack.
We have been buying the Tru Red plastic file boxes for the past few years and they are by far our choice. We use them mostly for storage of things besides files since you can see the contents and the quality is good enough to ensure safe storage and stacking. Good quality and a good value.
